This is a mandatory update, every one must update to this version before we reach the block with height 232,000. At this height the protocol will start rewarding accounts that find a block again. Block 232,000 is expected in three days from the moment of this release.

This version comes with a new byte format for the central blockchain/blocks file which is basically the physical blockchain inside HEAT. Because of the nature of the HEAT blockchain being a flat (memory mapped) file (instead of a database) a migration from one to the other format proved difficult. An easier solution was if users delete their current chain and download a new one from the network.

When running this version for a first time we automatically delete and redownload blockchain/blocks, this happens only once.

To make this process as safe as possible we've added two full chain checkpoints at height 185,000 and one at height 221,250. While you download and you reach that height a digital finger print (SHA256) of all previous blocks is created and compared to the finger print we hard coded in the source code.

This release disables heat.forgingDelay and heat.forgingSpeedup configuration options, this should equalize forging changes.
